Adios are not miracle pills and dont claim to be, although they def do fasten your metabolism....you can tell that by how many times you go to the toilet in a day. i am very healthy and not over weight but used these to loose a few pounds before my holiday....with a controlled diet i.e not too much fat and exercise these pills are great for speeding things up.....they are not going to work miracles but hey only surgery does things like that and even that doesnt last forever, the key is to look after yourself and remember "you are what you eat"
